Abstract
Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention relates to air cushion makers, and more particularly, to a film-aligning device for aligning a plastic film during a feeding stork, so as to ensure smooth inflating and sealing processes.
[0003] 2. Description of Related Art
[0004] For protecting packed objects from being damaged under accidental impact, buffer or cushion materials are generally used to fill void. As can be seen in FIG. 1, an air-bubble sheet made of plastic films is one of the most poplar cushion materials. A manufacture employs special equipments to produce such air-bubble sheet as a large piece, and a user can later cut or pucker the sheet at will to fill void in a packing case. However, the manufactured air-bubble sheet is space-consuming at transportation and storage due to its characters of being inflated and non-compressible. Thus, such air-bubble sheet is uneconomic and inconvenient in respect of transportation and storage.
